Ext.define is not a function

[arcobaleno]

In a Sencha Touch application I have defined some classes in a js file in the Resources section.
Like that:

Ext.define('Contact', {
    Insert: function() {
        //Code...
    },
    Delete: function() {
        //Code...
    }
 });

Connecting locally, with Architect running, the application runs properly, but if I 'Build web app' and I publish the application, then I get the error: 'Ext.define is not a function'.
How can I fix?

Architect version: 3.5.1.348
Framework: Sencha Touch 2.4.x
I tried to edit the file app.json to change the order of loading js resource, but in vain because it is regenerated every time you save.
Thanks for any suggestions.

Today I found that the problem lies elsewhere. I get the error: 'Ext.define is not a function' at startup, but I realized that my class is defined anyway.
The problem is that I add my class as an attribute of another class and this works in debug, whereas the attribute is undefined after publishing.

this.getMainNavigationView().push({
    xtype: 'Container',
    myProperty: Ext.create('Contact')
});

Is it a bug? Is there a workaround to solve the problem?

I tried to add attribute doing:

Ext.apply(theContainer, {myProperty: Ext.create('Contact')});

This works, but I need the property is present in the initialize of theContainer, so this doesn't solve.
Thanks to those who will help me.

In the class/file where you use Ext.create:

this.getMainNavigationView().push({
    xtype: 'Container',
    myProperty: Ext.create('Contact')
});

Add to the requires array the class Contact.

I tried to add the class Contact to the requires array, but I keep getting the error: 'Ext.define is not a function', however the application works the same.

I solved the problem of adding an attribute to a class, defining a new class, so if I wrote:

this.getMainNavigationView().push({
    xtype: 'Container',
    myProperty: Ext.create('Contact')
});

Only it works with Architect running, instead writing:

Ext.define('foo', {
    extend: 'MyApp.Container',
    myProperty: Ext.create('Contact')
}
this.getMainNavigationView().push(Ext.create('foo'));

This also works after publishing the application.

Thanks for the support.
